Please note that these are only mathematical estimates. The actual calories used by your body may be much higher or much lower depending on many factors, such as lifestyle, medical history and conditions, and family history. In particular, very active people, older people, or overweight people may use more or less calories than predicted.

BMI = Body Mass Index

A statistical measure which compares a person’s weight and height. Though it does not actually measure the percentage of body fat, it is used to estimate a healthy body weight based on a person’s height.

BMR = Basal Metabolic Rate

The number of calories that your body requires per day in a resting state. It can vary from person to person and depends on your eating habits, body composition, and activity level.

MET = The Metabolic Equivalent of Task

Metabolic Equivalent or MET, is a way of expressing the energy cost of physical activities. By convention 1 MET is considered the resting metabolic rate obtained during quiet sitting. MET values of physical activities range from 0.9 (sleeping) to 18 (running a 5.5 min/mile). MET is used as a practical means of expressing the intensity and energy expenditure of physical activities.
